Coil Ratings
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/−20% for AC rated current and
±15% for DC coil resistance.
2. Performance characteristic data are measured at a coil temperature of 23°C.
3. The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.
4. For DC-operated Relays with the LED indicator built-in, add an LED current of approx. 5 mA to the rated current.

Safety Precautions
■Safety Precautions for Correct Use
Installation
Recommend mounting MK-S Relay so that side with wiring diagram is facing down.
Handling
Check coil polarity when wiring LED Indicator and Diode Models.
Test Button
Do not use the test button for any purpose other than testing. Be sure not to touch the test button accidentally as this will turn the contacts ON.
Before using the test button, confirm that circuits, the load, and any other connected item will operate safely.
Check that the test button is released before turning ON relay circuits.
If the test button is pulled out too forcefully, it may bypass the momentary testing position and go straight into the locked position.
Use an insulated tool when you operate the test button.
Models with test buttons or LED indicators fulfill the requirements for reinforced insulation between live parts and the front of cover only when the
Relay is in a complete condition, i.e. with the nameplate, nameplate frame, test button, and slider in place. If any of these parts are removed, only
the requirements for basic insulation are fulfilled.

est in the Products until the full purchase price is paid;
d. Delivery and shipping dates are estimates only; and

portation bill signed by the carrier noting that the carrier received the Products
from Omron in the condition claimed.
13. Warranties. (a) Exclusive Warranty. Omron’s exclusive warranty is that the
Products will be free from defects in materials and workmanship for a period of

replacement thereof) the non-complying Product, (ii) repair the non-complying
Product, or (iii) repay or credit Buyer an amount equal to the purchase price of
the non-complying Product; provided that in no event shall Omron be responsi-
ble for warranty, repair, indemnity or any other claims or expenses regarding
the Products unless Omron’s analysis confirms that the Products were prop-
erly handled, stored, installed and maintained and not subject to contamina-
tion, abuse, misuse or inappropriate modification. Return of any Products by
Buyer must be approved in writing by Omron before shipment. Omron Compa-

15. Indemnities. Buyer shall indemnify and hold harmless Omron Companies and
their employees from and against all liabilities, losses, claims, costs and

tigation, litigation or proceeding (whether or not Omron is a party) which arises
or is alleged to arise from Buyer's acts or omissions under these Terms or in
any way with respect to the Products. Without limiting the foregoing, Buyer (at

tle any action brought against such Companies to the extent based on a claim
that any Product made to Buyer specifications infringed intellectual property
rights of another party.

“forbidden” or other proscribed persons; and (ii) disclosure to non-citizens of
regulated technology or information.
18. Miscellaneous. (a) Waiver. No failure or delay by Omron in exercising any right
and no course of dealing between Buyer and Omron shall operate as a waiver
of rights by Omron. (b) Assignment. Buyer may not assign its rights hereunder
without Omron's written consent. (c) Law. These Terms are governed by the
law of the jurisdiction of the home office of the Omron company from which
Buyer is purchasing the Products (without regard to conflict of law princi-
ples). (d) Amendment. These Terms constitute the entire agreement between
Buyer and Omron relating to the Products, and no provision may be changed
or waived unless in writing signed by the parties. (e) Severability
. If any provi-
sion hereof is rendered ineffective or invalid, such provision shall not invalidate
any other provision. (f) Setoff. Buyer shall have no right to set off any amounts
against the amount owing in respect of this invoice. (g) Definitions. As used
herein, “including” means “including without limitation”; and “Omron Compa-
nies” (or similar words) mean Omron Corporation and any direct or indirect
subsidiary or affiliate thereof.
Certain Precautions on Specifications and Use
1. Suitability of Use. Omron Companies shall not be responsible for conformity
with any standards, codes or regulations which apply to the combination of the
Product in the Buyer’s application or use of the Product. At Buyer’s request,
Omron will provide applicable third party certification documents identifying
ratings and limitations of use which apply to the Product. This information by
itself is not sufficient for a complete determination of the suitability of the Prod-
uct in combination with the end product, machine, system, or other application
or use. Buyer shall be solely responsible for determining appropriateness of
the particular Product with respect to Buyer’s application, product or system.
Buyer shall take application responsibility in all cases but the following is a
non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety equip-
ment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or prop-
erty. Please know and observe all prohibitions of use applicable to this Prod-
uct.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-
ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Omron Companies shall not be responsible for the
user’s programming of a programmable Product, or any consequence thereof.
3. Performance Data. Data presented in Omron Company websites, catalogs
and other materials is provided as a guide for the user in determining suitabil-
ity and does not constitute a warranty. It may represent the result of Omron’s
test conditions, and the user must correlate it to actual application require-
ments. Actual performance is subject to the Omron’s Warranty and Limitations
of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our prac-
tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica-
tions of the Product may be changed without any notice. When in doubt, spe-
cial part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Omron’s representative at any time
to confirm actual specifications of purchased Product.
5. Errors and Omissions. Information presented by Omron Companies has been
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors or omissions.
